GIS Valve: Reliable High-Pressure Safety for Steam Systems

The GIS Valve is a rugged, high-performance safety valve designed by Greno Industries in 1978 for the U.S. Navy. It’s been installed on 400+ Navy ships to boost safety and reliability in steam systems. Even today, it remains a trusted solution for non-nuclear ships.

Key Features

  • Built for extreme conditions: Handles pressure up to 3,000 psi and temperatures up to 1,100°F.

  • Remote operation: Adjust settings safely from a distance, avoiding exposure to high heat or pressure.

  • Leak-free design: Stops steam leaks for safer, more efficient operation.

  • Easy maintenance: Modular parts can be quickly replaced without shutting down the entire system.

Why It’s Better Than Conventional Valves

  • Precision control: Maintains steady boiler pressure, even at peak loads.

  • No wasted energy: Opens only when needed, saving fuel and reducing wear.

  • Built to last: Uses durable materials and eliminates weak points like exhaust piping.

  • Safety first: Works during power outages and protects operators during adjustments.

Cost Savings

  • Cut maintenance costs: Fewer parts to replace and no leaks to repair.

  • Simplify systems: Replace multiple valves with one efficient GIS Valve.

  • Upgrade flexibility: Custom-fit to your existing setup—no full redesign needed.
